Prefabricated　installation,　a　pivotal　study　in　the　realm　of　contemporary　construction　practices,　delves　into　the　utilization　of　prefabrication　within　mechanical,　electrical,　and　plumbing　(MEP)　systems.　Despite　its　ascending　prominence,　the　domain　grapples　with　ambiguities　in　application　pathways,　uncertain　developmental　trajectories,　and　the　absence　of　a　holistic　technical　paradigm.　This　research　endeavors　to　bridge　these　gaps　by　conducting　a　thorough　and　multidimensional　investigation　into　the　current　landscape　of　prefabricated　MEP　installation　initiatives.　This　study　meticulously　dissects　the　paradigm　from　five　critical　vantage　points:　historical　evolution,　standards　and　regulations,　life　cycle　analysis,　technological　applications,　and　corporate　implementation　strategies.　At　present,　there　is　still　a　lack　of　standards　and　specifications　specifically　for　the　field　of　assembled　MEP　installation.　The　analysis　reveals　a　trend　towards　intelligent　and　sustainable　installation　practices　in　prefabricated　MEP　projects.　The　research　predominantly　focuses　on　the　design,　production,　and　installation　stages.　Notably,　building　information　modeling　(BIM)　emerges　as　the　most　prominent　technology,　followed　by　the　Internet　of　Things　(IoT)　and　3D　laser　scanning,　with　extended　reality　(XR)　technologies　gaining　traction.　Large,　state-owned　construction　firms　are　spearheading　innovative　applications　in　this　realm.　In　summary,　this　paper　provides　an　overview　and　outlook　for　the　development　direction　and　the　application　of　cutting-edge　technologies　in　prefabricated　MEP　installation　projects,　with　the　aim　of　supporting　the　industry＇s　advancement.
